Be it known that We, CLAUDE ELLioTT and from the Cylinders, Valves, and Rings of Gasolene-Engines; and we dohereby declare that the following is a full and accurate description of the same.

The nature of our invention consists in the use of a fusible metal which when placed in the cylinders, valves and rings of gasolene engines will fuse at a certain heat and when fused will act upon the accumulated carbon and through the action of the machine remove and eliminate the carbon.

To enable others to understand the nature of our invention and apply it we will proceed to describe its composition and how it operates.

Our invention is a fusible metal composed of a mixture of lead, zinc, and pewter combined in such proportions (about one third parts of each) as will insure its melting at Specification of Letters Patent. Application filed January 13, 1912. Serial No. 671,141.

a given temperature, and assuming liquid form.

The metal so composed is placed in the fied metal to act upon the carbon lodged 0nthe parts and burn and expel it from the cylinder, valve or ring as the case may be.

What we claim as our invention, and desire-to secure by Letters Patent, is:

A method of removing carbon from the cylinder of an internal combustion engine consisting in placing a fusible metal or alloy in the cylinder and melting the same'by the heat generated in the cylinder.
